1.Find the increase in the boiling point of water at 100ºc when the pressure is inncrease by 2 atmospheres.Latent heat of vaporisation of steam is 540 cal/gm and 1 gm of steam occupies 1677 cm3 volume.

2.Calculate the change in entropy when 10 kg of water at 100ºc is converted into steam at the same temperature.

3.Show that etropy is the measurement of disorder in any thermodynamic process.
